They found only one Sky-Hook.

Elisabeth decided this is not a problem. Cyryl disagrees. 

Second picture in the OCs meet BioShock series, kinda, idk, there will be one more! Also, I tried to understand how Sky-Hooks and Skylines work with each other but lack of any reference pictures did not help. So don’t pay too much attention to that part of the picture please since I did not give much thought to it haha—-
